again on qt...

[Giorgi Lekishvili]

Juergen,
Thank you very much for the letter.

I'd agree with you that RH is mainly Gnome-based-distribution.
And I have qt-2.2.0, which comes with the distribution. The problem is that
>=qt-1.42 is mandatory.
Unfortunately, I cannot risk to upgrade the system, as most of packages
I use (I'm a computational chemist) are 2.2.x kernel-based.

Thank you anyway.
Regards,
Giorgi
